摘　　要：以苏州轨道交通11号线与苏州轨道交通3号线贯通改造工程为例,研究隶属于苏州轨道交通11号线的接口车站——唯亭站的信号系统改造方案。基于11号线唯亭站站场的变化,设计信号平面布置图,包含两线信号系统边界的重新划分、轨旁设备拆除与新增后的重新布置等;为实现两线列车以CBTC模式跨线运营,贯通改造采用并行冗余协议技术实现LTE与WLAN的车地无线双制式贯通;两线接口由继电接口改为CBTC邻站网络接口。并且对改造工程中其他既有站小交路运营数据的配置和相关影响项点,以及改造的工序逐个进行说明。该改造方案对后续类似的地铁改造项目有一定参考意义。Taking the renovation project of the connection between Suzhou Rail Transit Line 11 and Suzhou Rail Transit Line 3 as an example,the signal system renovation plan of the Weiting Station,interface station belonging to Suzhou Rail Transit Line 11 is studied.Based on the changes of Weiting Station yard of Line 11,the signal layout plan is designed,including the re division of the boundary between the two signal systems,the dismantling of trackside equipment,and the rearrangement after adding new ones.In order to achieve cross line operation of two trains in CBTC mode,parallel redundancy protocol technology was used to achieve wireless dual system connection between LTE and WLAN in train ground communication.The two line interface has been changed from relay interface to CBTC neighboring station network etc.Some data configurations for the operation of other existing stations and small loop and the related influence points,as well as the renovation process are also explained during the renovation of Weiting Station on Line 11.The renovation of the signal system at Weiting Station on Line 11 has certain reference significance for similar subway renovation projects.
